What's the goal here? We could have many more people each living in misery, crowding, and poverty. Or we could have fewer people with each one being rich and free and having access to parks and open space to breathe and relax.
More people isn't somehow good in itself. Children are great but one or two is enough.
A false dichotomy. The latter experience can be given to the former's population.
More people isn't somehow "good", but it's not bad.
How? Keep in mind only a small fraction of the world's population is even capable of being a tourist. Imagine how that changes when everyone is well-off enough to travel at will. Imagine your favorite beach, favorite museum, or your favorite national park and multiply the number of visitors by 10, 20, 40, etc. Waiting-lists for years to visit the Louvre. Prices so high that only the 1% of the 1% can afford to visit Maui.
Maybe you are assuming that VR will solve these issues? Perhaps a Matrix-like future awaits us.
Our wellbeing probably does rely on technology like VR and automation, but with so many mentally ill, I would say our current situation is already unacceptable (and has been for thousands of years). Adding billions more to the equation isn't going to help.
Earth doesn't have too many people. The people inhabiting it are just, currently, quite wasteful with resources.
